SPECIFICATION forming part of Letters Patent No. 278,667, dated May 29, 188?.

Application filed April 11, 1883. (No model.)

To all whom t't may concern Be it known" that I, ALEXANDER OLszEW- SKI, a citizen of the United States, residing at New. Jersey, have invented certainnew and useful Improvements in Apparatus for Producing Rods or Tubes of Celluloid or other Plastic Material; and-I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the. art to which it appertains to make and usethe same.

The invention has relation to anapparatus for formingor molding rods or tubes of cellu loid or other plastic material; and it consists in a meanswhereby a number of such rods or tubes may be formed simultaneously from one material is or may be compressed by a hydraulic ram or other suitable means.

The apparatusand method of producing the tubes orrods will be understood from the de scription hereinafter presented, reference bewhich- Figure 1 ,is a central vertical section of an embodiment of my invention. Fig. 2 repre sents a transverse horizontal section of same on the line so 00,- and Fig. 3 is a central vertical section of a modified form of thei-nvention,

' i In the accompanying drawings,A B denote twometal lic plates or disks, which are secured together at their edges, and the interior surfaces of which are so formed that whenthe ber, G, will heformed between them, said chamber extending, preferably, to a point adjacent to the edges of the disks. The lowerdisk, B,

the supply-pipe D, which is adapted,by a screw-thread upon its end or otherwise, to be attached to a supply chamber of reservoir, in which the material to be treatedis placed The preferred method of construction is to have the disk B cast with the supply-pipe D,

ed to engagea female thread in the supply chamber. In the upper disk, A, are provided which are screwed the nozzles F, the lower end of the nozzles opening into the'chamber' O, and their upper ends extending a suitable distance above the disk A. Any desired num-. ber of the nozzles F may be employed, accord ing to the will of the operator. Within the nozzle. F, and arranged to extend centrally through the same, are the rods G, the lower ends of which project throughthe disk B, and

are therein secured by the nuts H. Upon the rods G are formed the annular. shoulders I, which rest in sockets in the surface of the disk B,whereby and by means of the nuts aforesaid the rodsare prevented from moving in either direction. nozzle, and will extend, preferably, a slight distance beyond the outlet of same. The chamber O,formed between the disks AB, is clearly illustrated in Fig. 2. It will be observed that the chamber consists of portions radiating from the central supply-pipe, D, to points be yond the inletto the nozzles F. The form of chamber 0, however, is not of the essence of the invention, since it is obvious thatwhatever form will permit the flow ot' thematerial from the supply-pipe D to the nozzles will be eifective in carrying out the purpose tion. i

Around the supply-pipe D, and preferably of the inven One rod will be provided for each adjacent to the lower surface of the diskB, is

through it when desired or found necessary.

If the celluloid or other material passing through the supply-pipe D is stiff or hard, the introduction of steam into the chamberK will soften and cause it to flow more freely. When the flow of the material is too rapid the introduction of a cooling agent into the chamberK will serve to stiffen and retard the passage of the same. The disks AB are secured together, in the present instance, at their edges by the collars M, having'at opposite sides the ears N, which are connected by the bolts 0, as indicated in Fig. 2. The chamber K is, in the .presentinstance, formed by covering the an-.

'nular groove P with the metallic band Q, but

may be constructed in any other way which is especially adapted to' the production of tubes of plastic material, and its operation is as follows: The supply-pipe I) having been connected with the supply chamber or reservoir, the material is forced into the said pipe by means of a hydraulic ram or otherwise, according to well-known methods, the effect being that the material will flow into and fill every part of the chamber 0. Thence it will ratus I employ the disksA B, with the supply pipe D and nozzles F, as in the apparatus illus-' trated in Fig. 1, the same not having been changed in any essential respect. In this device, however, the disks A B are secured together by the thread formed upon the outer edge of the disk B, and by the thread formed upon the inner surface of the depending flange R of the disk A meshing therewith. When the disks A B are secured together the chamber 0 will be formed between them, as before, and will lead to the nozzles F.

It will appear obvious that the size and capacity of the chamber 0 may be increased or diminished by the relation the diskAbears to the disk B. For instance, if the disk A is screwed closeto the upper surface of the disk B, the capacity of the chamber 0 will be diminished, and if the disk A is not moved so,

closely upon the upper surface of the disk 'B the chamber 0 will be enlarged, and consequently its containing capacity will beincreased. By removing the rods G fronrthe apparatus illustrated in Fig. 1, it will appear plain that in the operation of the'device solid rods or cores G and closing the holes left by i rods of the material being manipulated, instead of tubes, will issue from the nozzles F.

It will appear'plaiu, also,that the disks A B may be secured together by any suitable means in addition to those illustrated in the drawings. For instance, bolts-may be passed through the disks A B beyond the line of or between the nozzles F, and the disks by that means secured together. The chamberKalso may be constructed in various ways, the one illustrated being only one convenient method of forming it. Upon the inner surface of the disk A is formed the inverted-cone-shaped projection S, which, when the disks are in position, projectsinto the upper end of the supply-pipeD and insures the free flow of the material equally into all parts of the chamber 0.

The apparatus illustrated in Fig. 1 may be used for forming rods by simply removing the them. The insertion of the cores G into the nozzles shown in Fig. 3 would adapt the apparatus therein illustrated for forming tubes instead of rods. The'nozzles and the cores or rods may be varied in their contour as may be desired, and in their construction it will be found desirable to make them of such size that they may be readily interchangeable at will. In the operation of the invention'the cores G may be extended any suitable length beyond the outlet of the nozzles F, and may be coated with a veneer of the celluloid or other plastic material being manipulated, according to well-known methods of coating springs and other articles.

I desire it understOOdthatT the invention herein described is not limited in its application to celluloid merely, but includes all kinds of compressible material. The invention may be used in the manufacture of lead pipes and other articles which needf not' beispecifically mentioned.
